Abstract (en)

[origin: EP3467329A1] A bearing sealing device includes two seals (inner and outer seals) sealing the space between the inner and outer races of a bearing to ensure higher seal performance, and also to reduce the area of the inner periphery of the outer race that needs to be ground. The bearing sealing device includes a ring (8) constituted by a metal annulus (32), and a rubber part (33). The metal annulus (32) is formed by cold pressing, and has a seal contact surface (30) kept in contact with seal lips (25 and 26) of the outer seal (7). The rubber part (33) includes a press-fitted portion (34) fixed to the inner periphery of the outer race (2). The inner race (1) has, on its outer periphery, a cylindrical fitting surface (13) to which the outer seal (7) is press-fitted.
